Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) is a drug-delivery method for patients with peritoneal metastasis (PM). The study objective was to investigate whether PIPAC is possible in an outpatient setting.

Data was extracted from the prospective PIPAC-OPC2 study ( NCT03287375). Patients with PM were treated by cisplatin and doxorubicin (PIPAC C/D), except patients with colorectal PM, who were treated by oxaliplatin (PIPAC OX). Patients were evaluated concerning the suitability for carrying out the PIPAC procedure in an out- patient setting. The preconditions for outpatient surgery were that the patient should be (1) freely mobilized, (2) adequately pain-relieved, (3) have untroubled urination and (4) without anxiety or discomfort caused by leaving the hospital.

During the study period, 106 PIPAC procedures (79 PIPAC C/D, 27 PIPAC OX) were performed in 41 patients with gastrointestinal or ovarian PM. Ninety percent (37/41) of the patients were pretreated with systemic chemotherapy. Eight patients (20%) received bidirectional chemotherapy. Twenty-four percent (10/41) of the first PIPAC procedures were completed in an outpatient setting, which increased to 65% (13/20) in PIPAC no 3 (p=0.008). In the PIPAC C/D cohort, 28% and 80% of the PIPACs were performed in the outpatient setting at PIPAC 1 and 3 respectively, contrasting to only 11% and 20% in the PIPAC OX group. No readmissions after outpatient care. Postoperative morphine administration was more frequent in the PIPAC OX group.

The PIPAC procedure can be performed in an outpatient setting. The critical component for success is pain control.
